Ketosense – An Arduino-based ketosis detector

And now for something completely different thanks to Jens Clarholm - his "Ketosense" device, the purpose of which is to detect the amount of acetone gas in someone's breath. The reason for needing to know this is to check if the user is in a state of "ketosis" - when your body runs on fats other than carbohydrates. The usual testing methods can be expensive or inconvenient, so Jens has hopefully saved a lot of money by using his Ketosense. It contains a temperature/humidity sensor along with an TGS822 ethanol gas sensor, and an LCD with various buttons for a user-interface. In the following video Jens explains the product:

That's certainly something which was unexpected, however a great demonstration of what's possible with an Arduino. For more details visit Jens' websiteAnd for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're interested in making adding your own LCD and control buttons to a project such as the Ketosense above, save time and move forward with the Freetronics LCD & Keypad shield which contains a bright 16x2 character LCD and five buttons that can be read from only one analogue input pin:
